Deciduous Trees and Shrubs Pruning Schedule
• Have an active growth season in spring and
sometimes summer
• Drop leaves in autumn
• Spring-flowering
• Summer-flowering
• Shade
• Fruit
• The best time to prune depends on the plant’s
growth and when it flowers
Evergreen Trees and Shrubs Pruning Schedule
• Evergreens do not shed leaves like
deciduous plants
• No obvious dormant season
• Pruning in winter months reduces
sap and resin flow
• Broadleaf Evergreens: Prune
before new growth in the spring
• Narrowleaf Evergreens (conifers):
• Needleleaf: Prune only when the
tan candle is present
• Scale-leaf: Prune before new
growth in the spring
